Title: Valve system for mixing suspensions - has valve stems interlinked by single operating component to move their stems simultaneously
Inventor: HEINZMANN HELMUT
IPC: D21F1/06
Filed: 1991-04-16
Abstract: The valve system to mix a number of suspensions in the papermaking industry is structured so that the valve stems are interconnected through a single operating component so that all the closures are operated simultaneously. The separate flow channels taper in the closing direction of the valves. The flow channels are arranged with the valve movement so that part of the valve gives an opening movement when the stem is operated and another part gives a closing movement. Pref. the valves are in line with each other, with a common valve stem, or the valve stems are parallel to each other. The flow channels are a mirror image of each other, and the valve movement is against each other. The flow channels next to each other are reversed so that they taper in different directions for the valve stems to be moved in the same direction each time. The valves are moved axially in different positions, and are held in place in each position. The valve stems rotate in the housing. The flow channels are formed by the outer surfaces of the valves and the inner surface of the housing. ADVANTAGE - The valve system is simple and accurately maintains a constant volume flow while the mixt. is changed from time to time, or maintains a constant mixt. while the volume flow is varied.

Title: Stacked fabric sepn. - uses contact pressure and adhesion applied to leading end of top layer to peel it off towards the centre
Inventor: GROSS JOHANNES DIPL ING
IPC: B65H3/32
Filed: 1991-04-16
Abstract: To separate the layers of fabrics in a stack and remove the top layer, the top layer (2) is partially lifted from the leading end (11) and the raising movement is continued to the centre zone of the layer. The top layer is then sepd. from the stack (3) in a movement continued through to the trailing end of the layer (2). The fabric lifting system is over the top layer (2) of the fabric stack (3) and then brought into pressure and adhesive contact with it, to roll it up from the leading edge in a peeling motion. The fabric (2) is lifted by a roller (1), rotating round a central axis, with an adhesive layer (4) to hold the material and carry it with the roller rotation. The adhesive layer (4) is pref. an adhesive tape, tacky on one side, with a rippled surface structure, while the non-adhesive side of the tape is held against the roller (1) by suction. The suction is applied to the adhesive tape through openings in the roller (1) surface and, when the suction is stopped, the adhesive tape can move in relation to the roller surface. The roller (1) is powered by a synchronised rotary and linear drive, where the rotary and linear speeds are equal. A separating blade (5) parts the peeled top layer (2) from the stack with a width that projects over both sides of the stack (3) and operates with a laying surface for the separated fabric layer, behind the separator blade (5). A stripper (7) covers the roller (1) width, parallel to its centre axis, and at a small gap from the roller surface, matching the roller shape to swing round the roller axis. A holder (10) can be lowered into contact pressure with the top layer (2) of the fabric stack (3). ADVANTAGE - The method allows thin and fine stacked fabrics to be sepd. into individual layers.

Title: Abrasive band finishing process for crankshaft journals etc. - involves measurement of journal size before and after each grinding cycle to determine required number of cycles.
IPC: B24B21/02
Filed: 1991-06-28
Abstract: The process relates particularly to workpieces such as crankshafts which have several journals to be finished and where the amount oversize may be different from one journal to another. In an abrasive band grinding process the abrasive band is pressed against the rotating journal by pressure shoes. At the end of a grinding cycle an indexing mechanism feeds unused abrasive band between the shoes and work. The size of a journal is measured before and after each grinding cycle and the measured value compared with the desired value for the journal. The difference between the measured and desired values is used to determine the number of grinding cycles required to bring the journal size inside the tolerance band. ADVANTAGE - Optimization of process.
Patent DE-4124881-A1 (DE)
Inventor: RINGS FRIEDEL
IPC: D06F39/02
Filed: 1991-07-26
Abstract: The invention concerns a device (1, 1a), similar in design to an ordinary wet vacuum cleaner, with a stock liquor container (2, 2a) comprising a tub-shaped bottom section (3, 3a) and a top section (4, 4a) which is hermetically mounted on the bottom section and is fitted with an integral suction fan designed to generate an underpressure in the bottom section (3, 3a). A suction line (5) leads out of the container (2, 2a) and into a container (7) of powder. The aim of the invention is to further develop a device of this kind so that stock liquor can be prepared from cleaning agent powder taken directly from the container containing it without producing any dust and the stock liquor thus prepared stored for feeding to industrial washing or washing-up machines. This is achieved by virtue of the fact that the suction line end (33, 33a) inside the stock liquor container is disposed at a point which is remote from the point of entry of the suction line (5) into the bottom section (3, 3a). In addition, a fresh water line (23) terminates in the container (2, 2a), the water outlet aperture (24, 24a) being disposed so that the water is directed on to the stream of powder passing through the suction line (5). The container (2, 2a) also has a stock liquor feed line (25) which is operatively linked to a pump (27, 61) to permit liquor to be pumped from an inlet (26) near the floor of the bottom section (3, 3a) and out of the container (2, 2a).
